High-energy radiographs are characterized by greater latitude compared to low-voltage radiographs. Latitude refers to the range of exposure levels that can produce an acceptable image on the film or digital detector. High-energy radiographs, which typically involve the use of higher kilovoltages (kV), have a wider latitude because they can successfully capture more variations in density and thickness of materials, allowing for more forgiving exposure conditions.

This characteristic enables high-energy radiographs to be more effective in imaging thicker and denser materials, as they can penetrate better, resulting in a clearer representation of internal features even if there are variations in material density or if slight over or under-exposures occur. In contrast, low-voltage radiographs are more sensitive to changes in exposure and have a narrower latitude, which can make them less effective for certain applications where consistency and variability in material thickness are involved.

The other characteristics mentioned in the choices, such as higher contrast or increased exposure time, do not inherently define the major distinguishing feature of high-energy radiographs. Higher contrast refers to the difference in densities captured, which can vary to some extent but is not specifically associated with energy levels. Similarly, increased exposure time is a factor influenced by multiple variables but does not relate to the
